ToaZZ whom it may concern-1' Beverly, in the county of Essex and State of Massachusetts, have invented certain 'lm-v provements in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in theseveral 1 7 it is, in some cases, desired to set the lowfigures.

This invention relates to machines for setting eyelets or other fasteners and one of its objects is to improve the feeding or spacing mechanism and render possible'certain novel operations in eyeleting machines.

vantageously in machines for setting lacing hooks, studs or similar articles.

More particularly, it is an object of the invention to provide feeding mechanism for an eyelet setting machine which shall have a' wide range of adjustment so that eyelet s of large diameter may be set with a very wide spacing and small eyelets may be set by the same machine with short or close" spacing.

A sufiiciently wide spacing for large eyelets is attained with difliculty bythe employment of feeding mechanism ofthe type disclosed in said patent above identified.

In that construction the'feeding movement of the work-engaging devices is limited by their connection with a pivoted controlling link. One method by which the range of this movement maybe increased in accord ance with the present invention is by substituting for the pivoted controlling link, means for guiding one part of the feed transmittingmechanism in a substantially rectilinear path and providing mechanism for changing the position of said guiding means, whereby a greater or'lesser resultant feeding movement is imparted to said work- Such construction will Specification of Letters Patent.

Another important feature of the invention consists in the provision 'of automatically operating means for regulating the ex tent "of the feeding movementin order that the eyelets or other fasteners may be set' automatically with varying spacing. V

er'most eyeletswith one spacing and the upper eyelets with 'a greater spacing, or to increase progressively-the spacing of the eyelets from the instep toward the top of the quarters. One method of effectingthese re sults, in accordance with the present inven tion, consists .in providing an adjustable lever for controlling-the extent of the feeding movement, and ail-intermittently acting cam or other device for regulating the'p'osition of said con-trolling lever. Prefer-ably,

the regulating cam mayflbel actuated by the movement of the feeding devices "and the de sired, operation may be attained by selectinga cam of suitable contour.

Other features of the invention, "relating particularly to. the construction of the automatic feed regulatingmechanism, consist in the provision of -means for preventing the over-running of the-regulating cam, and in providing a novel mounting for the reg1 ilating cam whereby 'it inay be readily removed to permit the substitution of-anotherj of different contour.

These and other features-of the invention 7 Q will" be best understood and appreciated from the following description of apr'e ferred embodiment thereof, selected for pur poses of illustration, in connection with the p accompanying drawings, in wliic'h-, V

Before proceeding to a detailed descri p-i tion of the various parts of the machine which comprise more particularly the subject-matter of this invention, it will be con- 7 venient to refer to the principal operative parts and their general mode of operation and relative arrangement. The machine illustrated in the drawings has a' frame ,2 which is, provided with bearings for the main shaft 4 adapted to be connected at one end, through a suitable driving clutch, with any convenient source of power and having a hand wheel 6 on the other end. The present machine, like that of said patent, com prises oppositely disposed punches 8 and oppositely disposed setting dies 10 arranged in bearings in a support or feed frame 12, with an anvil or die plate 14 also mounted in said feed frame, arranged between the oppositely disposed punches and setting dies. A guide plate 16 is mounted in the frame 2 and extends adjacent to the anvil 14 when the latter is in its initial position. Oppositely disposed spring presser feet are arranged to bear upon the sides of the guide plate 16 and serve to hold and guide the work properly as it is fed into punching and setting positions and edge gages 18 are also mounted on the guide plate.

In presenting work to the machine the two quarters of an upper are inserted between the opposite sides of the guide plate ;16 and the respective presser feet with their edges against the edge gages 18. The machine is then set in operation whereupon the punches are actuated to punch a hole in each quarter, then the feed frame 12 is moved rearwardly to bring the setting dies into alinement with the previously punched holes, and the eyelet raceways 20 are advanced presenting eyelets to the setting dies as the latter are actuated to set a pair of eyelets simultaneously in the two quarters.

After the setting dies have set the eyelets, they are released slightly but still held in engagement with the work, and then the feed frame 12 is moved to the left to feed the work a distance depending upon the spacing required between successive eyelets. The feed frame then makes its return movement, bringing the punches back to their initial position, and the operations are repeated.

A detailed description will now be given of the mechanism for carrying out the operations above outlined, including the novel mechanism and arrangement of parts for effecting and regulating the feeding of the work which constitute the subject-matter of the present invention. The feed frame 12 is pivotally connected by the spindle 24 at its rear end to the transverse arms of a forked bell crank lever'22. The bell crank lever 22 is fulcrumed on the frame by means of a pin 26 and carries a roller '28 running in a cam 30 on the shaft 4. The cam 30 is timed to shift the feed frame rearwardly which results in the feeding movement or the work, is effected by the cam 32 on the main shaft acting through the lever 34 and the transmitting links 36 and 38, the latter of which is pivotally connected to the feed frame and acts to swing the frame about the spindle 24 as an axis. The throw of the cam and the oscillation of the lever 84, is constant and accordingly the extent of feeding movement imparted to the frame would be constant if there were a direct connection between the lever 84 and the frame 12. In accordance with the present invention, however, it is proposed to resolve the lateral movement of the forward end of the lever 34 into components acting latterally and longitudinally and to transmit feed frame 12. By regulating the ratio of the two component movements the extent of the feeding movement and the distance between successive eyelets may be controlled. To this end, a roller 40 is mounted at or near the point of connection of the transmitting links 36 and 38 and disposed in operative relation therewith is a lever 42 having a straight guideway formed therein. The lever 42 is mounted on a short shaft 43, being movable over a segment plate 44 and may be maintained in any desired adjusted position by stop .pins inserted in holes in the plate. It will be apparent that when the lever is turned so that the guideway extends substantially at right angles to the lever 34 practically all of its lateral movement Will be transmitted through the links 36 and 38 to the feed frame. On the other hand, as the lever isswung carrying the guideway toward parallelism with the lever 84, more and more of the lateral movement of the lever is taken up by movement of the roller 40 longitudinally and the effective lateral movement becomes less and less, thus decreasing the extent of the feed ing movements of the feed frame 12.

Ordinarily the lever 42 is moved into position to give the desired spacing and maintained in such position during the eyeleting greater than theone before. To this end the spacing lever 42 is provided with an arm carrying a cam roller on i-ts'under side which projects into-the path of a suitably shaped edge cam 52 mounted below the segment plate 44 on a spindle 53. ,A tension spring 54 extending between the under side of the arm 50 and a stationary arm 56 serves to maintain the cam roller in contact with the periphery of the cam 52. The cam is actuated by a pawl and ratchet mechanism comprising a ratchet wheel 58 fast with the cam 52 and a pawl 60 yieldingly mounted in a carrying member 62 pivoted in the spin-,-

dle 53. The pivoted carrier 62 is oscillated by the transverse movement of the feed frame 12 throughthe lever (Stand the two connecting'links 66 and 68, the latter of which is pivoted to the forwardend of the feed frame. The oscillationof the carrier 62 maybe adjusted by shifting the point of connection of the link 66 with the lever 64. It has been found that thevrapid rotary movement imparted to the cam 52*during an,

sists in providing means for positively forc ing the pawl 60 against the ratchet wheel '58 at the end of its driving stroke so that relative movement of the ratchet wheel and pawl is prevented. To this end the pawl is provided with a contact piece 'l'O and arranged in the path thereof is a stop screw 74: projecting inwardly from a lug clownwardly extending from a stationary arm 72. -When it is desired to operatethe machine for uniform spacing, without-the automaticregulating mechanism, the pawl 58 may be withdrawn against the compression of its spring and maintained inoperative by giving the contact piece 70 a quarter turn. In

7 this position the contact piece will oscillate in a path below the stopscrew 7 4. c In the drawings the cam 52 is illustrated as having thirteen steps at progressively increasing radial distances from the spindle 53 and the ratchet wheel 58 is provided with thirteen corresponding teeth. The machine will, therefore, set thirteeneyelets at progressively increasing distances, an arrangement which is frequently desired ineyeleting womens boots. 1 7

In order that thecam 52 may be readily removed to permit the substitution of other cams having different contours the spindle 53 is provided with a pair of spring reta-ining arms 55 which normally expand and engage the hub of the ratchet wheel 58. The

cam 52 is mounted upon the hub of the; ratchet wheel and retained thereon by anut,

as clearlyshown Fig. By merely pressing the,arms;55 together the cam andtratchet 7 wheel may be slippedoff and others substituted. lnsteadwof employing a cam with thirteen equal" steps, it will be obvious that: cams ofvarious contours may be employed,

for example,.one having a, contour shaped toincrease the spacing while the first few eyelets aresetgand then'to decrease the spacingof the remaining eyelets',"or onehaving the first eyelets uniform and then increase the spacing of the remaining eyelets.
